9FGV1002B208NBGI

Overview

The 9FGV1002B208NBGI is a programmable PhiClock™ clock generator from Renesas Electronics, designed for automotive Ethernet and PCI Express (PCIe) applications. It features an integrated Phase-Locked Loop (PLL) and supports input frequencies via HCSL, LVCMOS, LVDS, or crystal sources. The device provides four differential output pairs with configurable signaling standards including LP-HCSL, LVDS, and LVCMOS, alongside two LVCMOS reference outputs. Operating within a temperature range of -40°C to 85°C, it meets AEC-Q100 automotive grade requirements. Key electrical parameters include a maximum frequency of 325MHz for differential outputs and 200MHz for LVCMOS outputs, with supply voltages ranging from 1.71V to 3.465V depending on the specific bank.

Feature Summary

• PCIe Gen1–Gen7 compliant with low jitter performance (< 41fs RMS typical phase jitter at 156.25MHz).
• Four programmable output pairs supporting spread-spectrum frequency generation and multiple I/O standards (LP-HCSL, LVDS, LVCMOS).
• Flexible configuration via hardware select pins or I²C interface with four unique addresses.
• AEC-Q100 qualified for automotive reliability with operation up to 85°C junction temperature.

Applications

• PCI Express (PCIe) timing solutions for Gen1 through Gen7 interfaces.
• Automotive Ethernet clock generation.
• Smart sensor and actuator systems requiring precise timing synchronization.

Procurement Notes

Verify the specific suffix 'B208NBGI' against the official 9FGV1002C datasheet addendum to confirm package type, tape/reel specifications, and any factory-specific labeling changes. Ensure compatibility with the required I²C address configuration and output voltage levels before procurement. Check current availability status as automotive components may experience supply fluctuations.

Selection Notes

Select this component when designing for PCIe or Automotive Ethernet applications requiring low-jitter clock distribution. Ensure the design supports the required output swing for LP-HCSL or LVDS standards. Verify that the system can accommodate the 1.8V core voltage and appropriate VDDO levels (1.8V, 2.5V, or 3.3V) for each output pair. Confirm that the I²C bus speed and pull-up requirements match the device's electrical characteristics.

Part Context

The 9FGV1002B208NBGI belongs to the Renesas PhiClock™ family of programmable clock generators. This series is optimized for high-performance timing in automotive and industrial environments. The base model 9FGV1002 offers flexibility through software configuration, allowing designers to tailor output frequencies and formats without changing hardware components, reducing bill-of-materials complexity.

Replacement Considerations

Direct replacements within the same family include other 9FGV1002 variants with different suffixes indicating package or reel options. Cross-family alternatives such as the RC2121 series may be considered for similar PCIe timing applications but require verification of pinout compatibility and jitter specifications.
